After missing the last train at a company drinking party, I stay at Manager Morisawa's home and discover she is an insatiable tease. Drunk and horny, she orders me into sex, but her technique is so good that I blow immediately. Once she learns I am a premature ejaculator, she toys with me even harder to see how many loads she can wring out. Her blowjob skills and dirty talk awaken unexpected stamina, keeping me hard and spilling semen forty times from Friday night through Monday morning.
